Senior P&O medewerker at Naturalis Biodiversity Center

Do you want to apply AI where it truly matters — protecting biodiversity? As senior machine learning engineer at Naturalis, you'll build and implement large-scale AI models and tools to understand biodiversity. Your work supports citizen science and helps track nature across the Netherlands.

As a senior ML engineer

You translate recent research into the functionality of the (specialized) AI models themselves.
You play an important role in the software development of the training pipeline for large scale models.
You get plenty of room to experiment and innovate and connect with colleagues in Naturalis and in our partner organisations, nationally and internationally.

This is what you'll be doing

As a senior ML engineer at Naturalis, you work together with colleagues and partners to meet the large AI ambitions of Naturalis. You develop the tooling for the development, evaluation and deployment of large scale multimodal foundational models. You use modern technologies in an organisation that highly encourages the usage of Open Source technologies. Furthermore you automate the deployment and integration of these models and support end users to help them develop their own models.

Your work supports high-impact programs such as ARISE and eDentity, which use AI, digital media, sensors, and DNA samples to monitor biodiversity and identify species. Because of you it is possible for researchers and partners to identify and analyse nature data. And of course you keep up to date with recent developments in deep learning and perform applied research of your own. Would you like to present your work in Naturalis to our European partners? We encourage collaboration and outreach!

Here's what we have to offer

A gross monthly salary of € 4,131.- to € 5,516.- for a full-time contract (36 hours).
End-of-year bonus of 3.4% of your gross annual salary and 8% holiday pay.
Time off thanks to 27 days of leave per year with full-time employment. Plus 1 extra day that you can use for a holiday that is important to you.
Travel allowance. Are you travelling by public transport, bicycle or on foot? Then you get €0.21 per kilometer. For commuting by car you get €0.125 per kilometer..
Pension scheme via PFZW, where Naturalis pays 60% of your premium.
A focus on your work-life balance. You can work partly from home and schedule your workday between 07.00 and 19.00.
Plenty of development opportunities. We support your growth and give you unlimited access to the online training platform Goodhabitz as well as creating a personalized development plan together.
Fascinating knowledge events. These help you stay up to date on the latest developments in both your own field and outside it, such as our lectures and gatherings on various (scientific) topics. You can also attend – or take part in – the fascinating internal information session Naturalis Draait Door.
A laptop and phone allowance.
Nice extras such as discounts on software and hardware for private use, collective health insurance plans, and a bicycle scheme. You’ll also enjoy discounts in our museum restaurant and unlimited free access to our award-winning museum for you and your family.
Fun team outings. We also get together for drinks every month, organise an annual BBQ and a fantastic New Year's party. Not your scene? That's fine too, of course. All team activities are voluntary.
A unique work environment in a state-of-the-art building where you will feel proud to work every single day – we guarantee it!
